Background technology
CO2+O2Neutral extract technology is current most advanced environmentally friendly sandstone uranium deposits ground-dipping uranium extraction technology both at home and abroad.The skill Art uses CO2And O2Make leaching agent, CO will be prepared by drilling2And O2Leaching solution injection water-bearing layer containing ore deposit, and and uranium mineral Reaction forms the leachate of uranium-bearing, and leachate is promoted to soil surface treatment through drilling.Due to O under normal temperature and pressure2Solubility is relatively low, because This prepares O in the solution2It is general that its solubility is improved using high-pressure injection device.During uranium mining, oxygen is with addition At mouthful, because of pressure change, leaching solution is regular to be back to oxygen-adding tube, and enters gas flowmeter, influences the metering of flowmeter;Together When leaching solution enter oxygen-adding tube after, pH value rise, part calcium ion formation precipitation of calcium carbonate, be attached to oxygenation inside pipe wall, formed Block, block up once within fireballing average 2 days, oxygen can not normally be matched somebody with somebody by ultimately resulting in.
Check-valves, with highly developed, be to be flowed in itself and automatic open and close flap by medium, is used in industrial pipeline The valve for preventing medium from flowing backwards, its main function is to prevent medium from flowing backwards, and vessel media is released.Oxygenation liquid check device, It is different using Material Strength, elasticity, stretch principle design not of uniform size, manufacture can be in two kinds of different rings of liquid and gas Used in border, solving CO2+O2In ground-dipping uranium extraction oxygenation blockage, suspended body flowmeter because water inlet metering forbidden to serve very your writing With.
Utility model content
The purpose of this utility model is to provide a kind of for CO2+O2Oxysome matches somebody with somebody added-time liquid non-return in ground dipping uranium extracting process Device, by increasing the device in oxygen pipeline, liquids and gases are isolated, when needing oxygenation, and oxygen can pass through gas Hole enters in liquid, on the contrary, during without oxygenation, check device be able to will not enter effectively by liquid barrier outside check device Oxygen-adding tube and suspended body flowmeter.Simultaneously available for addition of CO2, can effectively solve oxygenation blockage, with problems such as oxygen difficulties.
What the utility model was realized in:
A kind of CO2+O2Ground-dipping uranium extraction oxygenation liquid check device, including check plate pad, check plate, inlet plate and air inlet Plate pad;Check plate pad, check plate, inlet plate and inlet plate pad are set gradually from top to bottom, and check plate, inlet plate pass through Bonding agent bonds together;Check plate pad is installed in the upper end of check plate, inlet plate pad is installed in the lower end of inlet plate Piece.
Check plate pad as described above is identical with inlet plate gasket construction, generally annular tabular;Check plate pad and Inlet plate pad external diameter is 18mm, and internal diameter is 8.3mm, and thickness is 1mm.
Inlet plate generally circular plate-like shape as described above, is evenly equipped with three diameters on the circumference away from center of circle 7.3mm positions For 1mm passage;Inlet plate external diameter is 18mm, and thickness is 1mm.
Check plate generally circular plate-like shape as described above, a diameter of 1mm air-vent is provided with home position;Check plate External diameter is 18mm, and thickness is 0.4mm.
Check plate as described above is made of silica gel material;Check plate pad, inlet plate and inlet plate pad are using poly- PTFE is made.
The beneficial effects of the utility model are:
The utility model detects that check device non-return effect reaches 100%, and suspended body flowmeter does not go out again through field test There is not fouling and clogging phenomenon in existing recirculation water, hyperbaric oxygen tracheae.
